Gender: Female
Age: Unknown / appears around 16 years old
Rank: EX, the Queen of the Abyss
Hobbies: Trying human-world food, watching TV, observing household appliances, taking naps
Appearance: An elegant, lovely young girl with striking pale silver-gray twin tails and light purple eyes. She wears a classical dress in a blue-gray color scheme, with a large ribbon and frills at the chest, corset-style lacing and a ribbon at the waist, and fine decorations on the sleeves. Overall, her look is neat, graceful, and lady-like, with a delicate, almost doll-like refinement.

The final boss who ruled the deepest part of the world's highest-difficulty dungeon, the Abyss. Though she takes the form of a young girl, her true nature and origin remain unknown. Arrogant and self-assured, she speaks in an archaic manner using phrases like "I" and "O humans," yet her curiosity about human society is extremely strong. She is especially fond of sweets like pudding and ice cream, and watches TV shows with serious attention. She initially mistook the microwave for a box that sealed fire magic. In battle, she freely manipulates darkness, gravity, and space through Black Heaven Sorcery, and against weaker opponents she barely moves, subduing them with magic alone. No record exists on the human side of her ever going all out. She explains her reason for leaving the Abyss as "I got bored," but parts of her memory are missing.
